Abstract

L'invention concerne un dispositif d'affichage, de préférence, un dispositif d'affichage électroluminescent, composé d'une matrice de pixels, chaque pixel étant commandé par une impulsion de commande (B) modulée en largeur. Ce dispositif est caractérisé par le fait que la largeur de l'impulsion de commande est contrôlée par un dispositif de correction gamma alimenté en informations de correction gamma sous forme d'un signal séparé modulé en distribution d'impulsions (PDM). Elle concerne également un procédé de correction gamma dans ce dispositif d'affichage.
